Why This Recipe Works

What Is Tartar Sauce?

Tartar Sauce is a cold, mayonnaise based condiment rooted in European “sauce tartare,” adapted by home cooks around the world. It’s typically tangy, herby, and studded with pickles and capers so it complements fried and grilled seafood.

It’s creamy. And it’s sparkly with acid and brine that wake up fatty flavors.
Think of it as a bright, savory dip that refreshes the palate.

Introduction Detail 2

Origins are simple. A mayo and acid base dressed with chopped aromatics became the sauce we know today.
That straightforwardness is why the best Tartar Sauce is made at home you control the balance.

Ingredients & Substitutions

This Tartar Sauce ingredients list is purposefully short and flexible. I always recommend measuring, chopping fine, and tasting as you go.

• 1 cup mayonnaise (240 g) substitute: 1/2 cup mayo + 1/2 cup plain Greek yogurt or use avocado oil mayo for dairy-free
• 3 tbsp finely chopped dill pickles or cornichons (45 g) substitute: 2 3 tbsp dill or sweet relish (reduce added sugar if sweet)
• 1 tbsp drained capers, roughly chopped (15 g) substitute: chopped green olives (Castelvetrano) or omit and add 1 tsp extra pickle brine
• 1 small shallot, finely minced (about 2 tbsp / 20 g) substitute: 2 tbsp finely minced red onion
• 1 tbsp fresh lemon juice (15 ml) + lemon zest from 1/2 lemon substitute: 1 tbsp white wine vinegar or 1 tsp pickle brine
• 1 tsp Dijon mustard (5 g) substitute: yellow mustard or a pinch of dry mustard
• 2 tbsp fresh flat leaf parsley, finely chopped (8 g) substitute: extra dill or chives
• 1 tsp finely chopped fresh dill (optional) (2 g) substitute: 1/2 tsp dried dill or omit
• 1/4 to 1/2 tsp granulated sugar substitute: honey or omit if using sweet relish
• Salt and freshly ground black pepper, to taste
• 1 2 tsp milk or water, only if you want a thinner consistency substitute: a splash of pickle juice

Chef's Note: Drain pickles and capers very well before chopping. Excess brine throws off the balance and makes the sauce too thin or overly salty.

Ingredient	Substitute

Pickles/cornichons	Dill or sweet relish
Capers	Green olives or extra pickle brine
Shallot	Red onion
Lemon juice	White wine vinegar or pickle brine

Flavor Building Components

This Tartar Sauce leans on three pillars: fat, acid and texture. Fat from the mayo carries flavor; acid from lemon and brine brightens; crunchy mix-ins provide mouthfeel.
When you layer them carefully, the sauce tastes complex despite being only a few ingredients.

Ingredients Detail 1

Mayo is the glue. It smooths and holds the acid so nothing tastes harsh.
Use full fat mayo for the classic mouthfeel.

Ingredients Detail 2

Pickles and capers are the personality. They bring pops of vinegar and salt that make fried fish sing.
Chop them fine so every bite is balanced.

step-by-step Instructions

Making Tartar Sauce is mostly chopping and tasting. This Tartar Sauce comes together in ten minutes, then it benefits from a chill.

1. Prep aromatics and pickles. Finely mince the shallot, chop pickles/cornichons and parsley, and roughly chop the capers. The pieces should be small and uniform so textures sing in every spoonful.
2. Combine base ingredients. In a bowl, whisk 1 cup mayonnaise with 1 tsp Dijon mustard and 1 tbsp fresh lemon juice until glossy and smooth. Add lemon zest now if using for extra brightness.
3. Fold in mix-ins. Stir in pickles, capers, shallot, parsley, dill (if using), and a pinch (1/4 tsp) sugar only if the mixture needs rounding. You want flecks throughout, not big chunks.
4. Season and adjust. Taste and add salt and pepper in small steps. If it’s too flat, add 1/2 tsp more lemon juice or 1 tsp pickle brine. If it’s too sharp, a dash more mayo calms it.
5. Chill to meld flavors. Transfer to an airtight container and refrigerate at least 30 minutes (up to 24 hours) so the flavors marry. Give it a final stir and taste before serving.
6. Thin if needed. For fish tacos or a drizzling sauce, whisk in 1 2 tsp milk or water until it reaches desired pourability.

Assembly & Customization

This Tartar Sauce can be kept classic or nudged toward herb forward or spicy.

• For lighter calories: swap half the mayo for plain Greek yogurt.
• For herb forward: double the dill and cut parsley.
• For heat: add 1 tsp chopped cornichon jalapeño or a half teaspoon hot sauce.

Instructions Detail 1

Make it ahead. Flavor deepens after a rest in the fridge.
Trust me day-of tastes better than minutes after.

Instructions Detail 2

Want a creamier, tangier version? Add a splash of caper brine and up the Dijon.
Small adjustments go a long way.

Chef's Tips & Common Mistakes

People often overdo one thing. Stop. Taste as you build.

• Mistake 1: Dropping in wet pickles. Fix: Pat pickles and capers dry on paper towel before chopping.
• Mistake 2: Skipping the chill. Fix: Refrigerate at least 30 minutes so flavors meld; serving immediately makes it taste "raw."
• Mistake 3: Adding too much acid at once. Fix: Add lemon or brine in small increments and taste between additions.

Storage & Freezing

Store this Tartar Sauce in an airtight jar in the refrigerator for 4 5 days ; label the date.
Freezing is not ideal for mayo based sauces, but you can freeze small portions for up to 1 month : spoon into an ice cube tray, freeze solid, then transfer cubes to a freezer bag.

Thaw overnight in the fridge and whisk vigorously to re-emulsify.
Do not microwave. If you want it warm, let it come to room temperature for 20– 30 minutes and whisk; or place the sealed jar in a bowl of warm water for a few minutes and whisk immediately.

Recipe FAQs

How long will homemade tartar sauce last in the refrigerator?

When stored in an airtight container in the refrigerator, homemade tartar sauce typically lasts 3 to 4 days. Since this is a cold, uncooked sauce based primarily on mayonnaise, you should strictly adhere to the use-by date of your commercial mayonnaise base.

Why is my tartar sauce too watery or thin?

The most common cause of thin tartar sauce is excess liquid introduced by the pickle relish, chopped pickles, or capers. Ensure you thoroughly drain all briny additions before mixing them into the mayonnaise base.

If the sauce is already thin, stir in an extra spoonful of thick mayonnaise or sour cream to help re-emulsify and thicken the mixture.

Can I make this tartar sauce suitable for a vegan diet?

Yes, this recipe is easily adaptable for vegan diets by replacing traditional mayonnaise with a high-quality vegan mayonnaise substitute. Since the other ingredients (pickles, capers, herbs) are typically plant based, no other major changes are required.

This modification maintains the signature creamy texture and tangy flavor.

Can I substitute other ingredients for capers or dill?

Absolutely; the flexibility of tartar sauce allows for great customization based on your pantry. For a caper substitute, finely chopped green olives or pickled banana peppers provide a similar briny, salty punch.

If fresh dill is unavailable, you can use tarragon, chives, or parsley to maintain a fresh, herbaceous element.

The sauce tastes bland; how do I adjust the flavor balance?

Tartar sauce requires a strong balance of acidity and salt to cut through rich fried foods. If your sauce is bland, add an extra squeeze of fresh lemon juice or a small splash of white wine vinegar, along with a final pinch of sea salt. Tasting and adjusting these elements is the key to perfect seasoning.

Is it safe to freeze leftover tartar sauce?

No, freezing tartar sauce is strongly discouraged because the mayonnaise base is an emulsion that will break during thawing. The sauce will separate into an unappealing, oily, and grainy texture once defrosted. Always plan to consume the sauce within its refrigerated shelf life.

Is it necessary to let the tartar sauce rest before serving?

While the sauce is ready immediately, allowing it to rest for at least 30 minutes in the refrigerator greatly improves the flavor. This resting time allows the chopped herbs, capers, and pickles to release their essential oils and juices, fully infusing the mayonnaise with complex, tangy flavor.
